Abstract
The invention relates to a drilling device comprising a drilling machine (), which has a drilling spindle () that is rotatably supported in a machine housing (), and a drilling chuck (), which has a chuck body (), a clamping cone () that can be rotated coaxially to the chuck body (), and a jaw holder (), in which clamping jaws () are guided in guiding receptacles (), which clamping jaws are supported on a carrier () so as to be radially movable, the threaded section () of which carrier engages in a threaded socket () that is associated with the chuck body () and that is coaxial to the chuck axis. The drilling spindle () is designed as a hollow spindle, in which a coupling rod () that is connected to the threaded socket () in a rotationally fixed manner engages, wherein the coupling rod () can be moved between a clamping position coupled with the machine housing () in a rotationally fixed manner and a drilling position coupled with the drilling spindle () in a rotationally fixed manner.
